Research in accumulation focuses on the process by which substances or particles gather or build up over time. This research area often includes studying how accumulation occurs in various systems such as environmental pollutants in soil or water, toxins in the human body, or financial assets in investment portfolios. Researchers may investigate the factors that contribute to accumulation, the potential impacts of accumulated substances or particles, and ways to mitigate or control accumulation for various purposes. This research area can involve interdisciplinary approaches and draw from fields such as environmental science, chemistry, economics, and public health.
